Subject[PATCH net-next 2/3] ptp: clockmatrix: Remove IDT references or replace with Renesas.
Date
From: Vincent Cheng <vincent.cheng.xh@renesas.com>

Renesas Electronics Corporation completed acquisition of IDT in 2019.

This patch removes IDT references or replaces IDT with Renesas.
Renamed idt8a340_reg.h to clockmatrix_reg.h.
There were no functional changes.
